<p>This shouldn’t be a particularly hard problem, from a cursory glance we don’t correctly detect edition for files after parse phase in the compilation analysis</p>

<p><span class="user-mention" data-user-id="153740">@Igor Matuszewski</span> in general, I think it'd be correct to assume that a file is at least 2018 edition if it uses <code>async fn</code></p>

<p>might be a bit harder for async blocks because of stuff like <code>if async { ... }</code></p>
